Using the DC Sports Front Strut Bar on your Kia Stinger is easy. First, make sure your vehicle is parked on a flat and stable surface. Then, install the strut bar between the two strut towers as per the provided instructions. When driving, you'll notice improved handling right away. As for maintenance, it's a good idea to check the connections periodically to ensure they're still tight. If you live in an area with a lot of road salt or harsh weather, you might want to clean the strut bar every few months to prevent corrosion. Avoid over - tightening the connections as this could cause damage. Also, don't drive on extremely rough terrain that could put excessive stress on the strut bar.
